How much and when? Snow is coming

So we are going to get snow this afternoon. That leaves us with two questions: How much are we going to get and what time is it going to start?

Light snow has started falling in Pittsburgh and the storm is slowly moving across the state

There is a Winter Weather Advisory in effect from 4 p.m. through 1 a.m. Saturday. Flakes will start falling here around 4 p.m. The evening commute will see accumulating snow, maybe as much as an inch. This is not a big storm, we likely will not get much more than a coating to a couple of inches, but with the frigid temperatures, road surfaces will get slick.

The snow will likely stop around midnight. Total accumulations will run 1-3 inches, just enough to force you to break out the shovels in the morning.

The sun will peek out on Saturday, but the nasty cold will stick around all weekend before temperatures start to moderate on Monday.

We also have our first cancellation to report. Radnor schools have cancelled all after-school activities for this afternoon and tonight. Saturday events are still on.
